Physics Final Exam Review (Ch. 2, 3, 4, 6, 7, 12)

Front

What is a natural satellite?

Back

A natural satellite is a celestial body that orbits a planet or a larger body, such as the Moon orbiting Earth.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

According to Newton's second law, acceleration is inversely proportional to mass when a constant force is applied. Therefore, an object with less mass will accelerate more than an object with more mass.

Front

Define velocity.

Back

Velocity is the speed of an object in a specific direction.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined. It determines the object's acceleration.

Front

What force keeps planets in orbit around stars?

Back

Gravity is the force that keeps planets in orbit around stars.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is the law of universal gravitation?

Back

The law of universal gravitation states that every point mass attracts every other point mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.
